How to view changes to an OpenNeuro dataset draft

OpenNeuro has implemented a data retention policy, stating that datasets that have been in draft state for greater than 28 days may be reverted to the latest snapshot. Unfortunately, we don't currently have an interface for viewing what changes have been made since the last snapshot, so users may not know whether they want to create a new snapshot or not.

This gist shows two ways to view the changes using the OpenNeuro CLI. We will use ds000001 as an example.

Download and diff

The easy but slow approach would be to use the CLI to download two copies of your dataset, the most recent tag and the draft, and run diff -r on the pair:

Partially-parametric permutation testing

Cluster thresholding in multi-voxel pattern analysis (MVPA) is an open problem, as many figures of merit are possible, few (if any) of which have been sufficiently analyzed to permit a parametric solution or a guarantee of compatibility with pre-computed simulations. Stelzer, et al. 2012 represents probably the most conservative approach, constructing voxel-wise and then cluster-wise null distributions at the group level, based on permuting the training labels at the individual level.

In Mapping the cortical representation of speech sounds in a syllable repetition task, we adapted this approach to skip the voxel-wise null distribution,
